Perhaps initially, but WAN PHY and 10GBASE-ER is being used widely today
and have for 1-2 years. WAN PHY was (imho) hindered by there not being any
practical implmentation of it until 2005 or so. 10GBASE-ER was also
hindered by limited availability, but now both technologies are in wide
use. So yes, short term they might not have been successful but that was
also caused by vendors not knowing what to charge for it. Some thought WAN
PHY would compete with their POS business, and wanted to price it half-way
between POS and 10GE LAN PHY, which of course is not good if you want
volume. Nowadays there are vendors that charge no premium for WAN PHY at
all.
So both WAN PHY and 10GBASE-ER are extremely usable technologies and we
would have been at a great loss if they weren't available today.
